The organic potassium-ion batteries (OPIBs) combine the advantages of organic electrode materials and potassium metal, showing great promise as secondary batteries. Research progress on OPIBs is summarized based on different types of electrode materials, including organic small molecules compounds, polymers, and frameworks. The review also provides insights into the research prospects and outlook for OPIBs.
The integrated advantages of organic electrode materials and potassium metal make the organic potassium-ion batteries (OPIBs) promising secondary batteries. This review summarizes the latest research progress on OPIBs according to the different types of electrode materials (namely, organic small molecules compounds, polymers, and frameworks (metal-organic frameworks (MOFs), covalent organic frameworks (COFs)). Additionally, the research prospects and outlook for OPIBs are also provided.
